Error during wrapup: NAs are not allowed in subscripted assignments
As far as I can see, I have no NA in the lhs (not after the second

Dear R-help,
I am reading strings (varchar) from MySQL database
and instead of some characters get garbled chars.
Strings are encoded in UTF-8. I have tried to change
encoding in MySQL to latin7, but it does not help.
I was not able to find solution, how to get strings
in proper encoding/form.
Here is one way of doing it. To write out 1 million rows on my system
took 21 seconds.

I doubt that you have a dataframe with those features, since R would
not allow such an event; more likely you have data in a file. If your
goal is to determine the number of items, then you should definitely
look at:
?count.fields
count.fields(filename, sep=",") # would give you 1 + the n

I simply want to print the data out. Surely, this data
will be manipulated (with Excel or other
programming languages) by other people suit to their purpose.
Typically the
What exactly is the problem you are trying to solve. What is going to
be done with the data? Is it going to be read by some other program?
How much physical memory do you have on your machine? Is there paging
occuring due to the size of the objects? Have you consider creating a
structure with 1

Dear all,
I found that printing with 'cat' is very slow.
For example in my machine this snippet
__BEGIN__

Yes, there are: replicate and quantile are your friends.
You will find better support in the R-Finance list, though.
